提出了铁路提速遇到的轨向平顺性问题,介绍了平顺性对铁路提速的影响,分析了在利用小型轨道检测装置检测轨道几何形位时,影响轨向不平顺检测精度的几个因素:弦测法原理影响轨向不平顺检测精度;“以小推大”所带来的误差影响轨向不平顺检测精度;由小车单边计算里程所引起的轨向检测误差等,并提出了相应的改进方案.
The problem of ride comfort is analyzed. The influence of ride comfort on the speed of railway is introduced. Some factors that affect the accuracy of track irregularity detection are analyzed when the track geometry is detected by a small orbit detection device. The principle of chord measurement affects the detection accuracy of track irregularities; the error caused by “small push” affects the detection accuracy of track irregularity; the error of track detection caused by the unilateral calculation of the carriage, etc., and proposes the corresponding Improvement program.
